Relationship of George Floyd protests to increases in COVID-19 cases using event study methodology

Area of Science:

• Epidemiology
• Public Health
• Infectious Disease Dynamics

Background:

• Investigated the impact of widespread protests, stemming from the George Floyd incident, on COVID-19 transmission.
• Focused on eight US cities with large-scale demonstrations.

Purpose of the Study:

• To determine if large public gatherings during protests correlated with significant changes in COVID-19 infection rates.
• To assess the role of social distancing non-compliance in disease spread within urban environments.

Main Methods:

• Employed event study methodology with a 30-day estimation period.
• Analyzed COVID-19 growth rates in cities where stay-at-home orders had been lifted for at least 30 days prior to protests.
• Compared infection rate trends before and after protest events.

Main Results:

• All eight studied cities exhibited positive abnormal growth in COVID-19 infection rates post-protests.
• Six of the eight cities demonstrated statistically significant increases in infection rates.
• Observed a clear correlation between protest-related gatherings and heightened viral transmission.

Conclusions:

• Violations of Centers for Disease Control and Prevention (CDC) social distancing guidelines during protests led to a significant rise in COVID-19 cases.
• Emphasized the critical need for strict adherence to public health recommendations during large-scale events to curb pandemic spread.
• Findings underscore the public health risks associated with mass gatherings amidst ongoing viral outbreaks.
